BUG: drop pyqt5 dependency in docker for linux/arm

[Alvaro-Kothe]

• closes Metadata generation failed when installing PyQt5 #61037 (Replace xxxx with the GitHub issue number)
• Tests added and passed if fixing a bug or adding a new feature
• All code checks passed.
• Added type annotations to new arguments/methods/functions.
• Added an entry in the latest doc/source/whatsnew/vX.X.X.rst file if fixing a bug or adding a new feature.

---

• The main problem is that PyQt5 doesn't provide pre-compiled binaries for linux-arm64.
• This solution is based on the suggestion from Fix/devcontainer qt deps #61611 (comment)
• Before installing the dependencies with pip, I remove the PyQt5 dependency with sed
• The flags in sed are case-Insensetive and delete.
• I added a new CI job to test the build on arm64, just to verify if my solution works. I can remove it later if needed.

I'm OK with the Dockerfile changes here, but I don't want this to creep too much into our standard CI stack

[WillAyd]

I don't think we should add arm as a platform in CI, not at least without a better use case for it

[Alvaro-Kothe]

It was just to check if the changes were successful. I will revert these changes now.

Great thanks @Alvaro-Kothe
